>>> I'm a bit surprised by the replies talking about serving millions of requests a second, or needing ultra-consistent packet latency. Perhaps most of the HN demo is working for companies that operate at that scale.

There is a high concentration of serious professionals on HN running world class operations. There is also a large amount of startup and single man operations who would hate to write a $100 check.

The thing is, one can only be on one side. Then the other side has nothing valuable to say to you, all their advice is misplaced.

So, to answer your question. It's stupid to ask what apps will reach a large scale. You're either at large scale already or you are not. Obviously, the article is only intended for small scale operations (actually, the entire article is just a generic ad, digitalocean has a nice affiliate program).
